Evidence for Colour-Octet Mechanism from CERN LEP2 gamma gamma -> J/psi + X Data
M. Klasen, B. A. Kniehl, L. N. Mihaila +1
We present theoretical predictions for the transverse-momentum distribution of J/psi mesons promptly produced in gamma gamma collisions within the factorization formalism of nonrel…
Nonabelian alpha_s^3/(m_q r^2) heavy-quark-antiquark potential
Bernd A. Kniehl, Alexander A. Penin, Vladimir A. Smirnov +1
We calculate the leading mass-suppressed two-loop contribution, proportional to alpha_s^3/(m_q r^2), to the potential of a heavy quark-antiquark system. This contribution originate…
The Algebraic Method
P. A. Grassi, T. Hurth, M. Steinhauser
Combining the effect of an intermediate renormalization prescription (zero momentum subtraction) and the background field method (BFM), we show that the algebraic renormalization p…
